Reports calls to <code>Enumeration</code> methods that are used on collections and may be replaced with equivalent
<code>Iterator</code> constructs.
<p><b>Example:</b></p>
<pre><code>
  Enumeration&lt;String&gt; keys = map.keys();
  while (keys.hasMoreElements()) {
    String name = keys.nextElement();
  }
</code></pre>
<p>After the quick-fix is applied:</p>
<pre><code>
  Iterator&lt;String&gt; iterator = map.keySet().iterator();
  while (iterator.hasNext()) {
    String name = iterator.next();
  }
</code></pre>
